CATHODIC PROTECTION FOR MARAGING-STEEL PROPELLERS

The maraging-steel propeller must be controlled to closer limits than that of the copper-alloy propeller since excesive cathodic polarization can lead to hydrogen embrittlement of the material. This makes it desirable to use an automatic impressed current system in order to control the potential of the propeller to the optimum level during sea service. A study was made of the distribution of electrode potentials over the propeller surfaces and electrical resistance between the propeller and ship hull.
